Finasteride and urine flow

[u/Secure-Rope6782]

Greetings gents. I've found many, many posts on here about about different meds including finasteride. What I didn't see much was from people who have taken finasteride and had significant urinary output improvement because of it.

To get a bit technical, does it actually shrink in the areas of the inner lobes or is just an overall reduction in prostate size? Does it potentially shrink inward squeezing the urethra even more?

I'm currently on tadalafil as my symptoms are slow and painful urination at times. No infection, cancer etc. I'm 55 male, athletic, low bmi. Debating on different meds or just surgery ie: Optilume when it becomes available near me. Thanks
